League and Carlson Follow-Up

In a post earlier this week I took a look into the recent struggles of Brandon League and Jesse Carlson. While there was some statistical evidence, it felt like I had just scratched the surface on explaining the downward spiral of these two pitchers who at one point were two of the most prized relievers in the Blue Jays bullpen.

Drew from Ghostrunner on First suggested that I venture a little further down into the rabbit hole and immerse myself in the statistics that would scare away an otherwise casual baseball fan. A few days later, after crunching the numbers and combing through pages and pages of statistics, I think I've come up with some more detailed explanations for Brandon League and Jesse Carlson's problems in 2009.

Just like Ghostrunner on First indicated earlier this season, Jesse Carlson was very lucky in 2008 with an suspiciously low .235 BABIP (Batting Average On Balls In Play). All signs pointed towards a BABIP increase in 2009 (which it did), along with Carlson’s ERA, and FIP numbers among others.

Brandon League’s BABIP in 2008 hovered right around the league average at .271. This year, it’s shot up 51 points to .313, which could also be another indication of League’s problems this season.

It’s hard to believe it, but the Blue Jays were actually better defensively for Carlson and League in 2008 than this season. Both Carlson and League’s DER (Defensive Efficiency Ratio) have taken a hit in 2009, and thus less outs means more runs against these pitchers.

Finally, we look at FIP (Fielding Independent Pitching). This stat takes all the fielders out of the equation and only reflects on what the pitcher does. It’s interesting to note that Jesse Carlson’s FIP has risen this year whereas Brandon League’s FIP has actually decreased.

Looking at these splits, we can see where the problem areas are for Brandon League and Jesse Carlson. But which situation do they perform the best? The answer might surprise you; Carlson actually holds opposing hitters to a lower average when he enters the game with runners on base and/or in scoring position. It’s almost like night and day – with runners in scoring position, Carlson’s opposing AVG is .229. With the bases clear, Carlson’s average skyrockets 77 points to .306.

Although not as drastic, Brandon League’s batter vs. pitcher stats also tell a story of where his troubles and strengths lie. Often as the second or third reliever to appear in the game, League is accustomed to entering with runners on base. Strangely though, his best numbers are when he begins an inning fresh with nobody on and nobody out.

So what results can we take from this? If I were Cito Gaston, I would play the percentages and use Jesse Carlson in high leverage situations with runners on base ... as crazy as that sounds. Brandon League is best served as a late-inning relief guy who can start and finish off his own inning, rather than take over for another reliever.

Nice work Ian. I would have never guessed that Carlson pitches a OPS of .615 with RISP. I guess it's because of all those solo homeruns. I'm so used to seeing him turn and look up after a pitch. And so used to the game getting further out of reach as he does so.

On the other hand, League is much more "generally bad", though the OPS none on/out is .601.

So ... if we're only dealing with these 2 pitchers, I would let League get the first out, then he would inevitably put someone on base with one or two out (let them steal second if it's only a single ... ok, not really), then bring on Jesse, but not until there are baserunners.

I'm just not sure I agree with letting League start and finish his own inning - his OPS jumps almost .150 after that first out with nobody on. Then once the runner is on, he's very clearly screwed.

Thanks for the link to that article, Mike. Good find! I was kind of surprised to see that League was second on the list to get the least help from the umpires with called balls and strikes. We can now add that as another variable to explain his struggles in 2009.

QJays, that was one of the weirdest things I noticed was that Carlson's opposing AVG is actually lowest with RISP. Now whether he causes those runners to get into scoring position or if they are inherited runners remains unknown.

With League, he's usually either lights out or he runs into trouble and another reliever has to clean up the mess. If League doesn't have a 1,2,3 inning, then that's a good sign that things are probably going to get ugly.

I'm cool with calling Carlson "Solo Man" - this year alone, 5 out of the 6 HR's he has given up have been solo shots. Even worse, 3 of those HR's came when the game was tied (one was a walk-off).

League is trully one of, if not the best, most frustrating pitcher. He should strike out every batter he ever faces with his filthy stuff. Carlson's ceiling I would describe as serviceable. I'm not sure he's going to last I'm the majors much longer. I Hope I'm wrong for his sake.

Awesome post though. Gonna have to come and visit this blog more often...
